Search and read FDA Recognized Consensus Standards records from your own code: the consensus standards FDA recognizes for device submissions: extent, transition dates and product codes, cited by recognition number. Published by U.S. Food and Drug Administration ([www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfStandards/search.cfm](https://www.accessdata.fda.gov/scripts/cdrh/cfdocs/cfStandards/search.cfm)); answered from Assyro's copy, refreshed daily 13:00 UTC.

Licence: public domain (see the [terms](https://open.fda.gov/terms/)). Each record links to its page at the source.

Example: "Does FDA recognize ISO 10993-1:2025, and in full?"
